Unstable angina and non-ST-segment elevation myocardial infarction: an analysis by TIMI score
Critical Care volume 13, Article number: P36 (2009)
The TIMI score was created to categorize the patient's risk of death and ischemic events, providing the basis for therapeutic decision-making. In the present study, the characteristics of patients with acute coronary syndrome (ACS) were analyzed using the TIMI score.
Materials and methods
From October 2003 to February 2009, data for 740 patients with ACS were collected prospectively; 570 (77.0%) were classified by TIMI score. From these 570 patients, 327 (56.21%) were admitted with unstable angina and non-ST-segment elevation myocardial infarction (NSTEMI). Statistical analysis was made with the chi-square test with Yate's correction.
Out of the 327 patients, 148 (45.2%) had unstable angina and 179 (54.8%) NSTEMI. The mean age was 64.2 years and 64.8% were men. The details of each group of TIMI score are presented in Table 1. The mortality in the group submitted to angioplasty was 0%, in the group submitted to coronary artery bypass graft surgery (CABG) was 0.8% (one patient) and in the group submitted to clinical treatment was 7.2% (15 patients). In the group submitted to CABG, two patients were submitted to thrombolytic therapy (TIMI score 3 and TIMI score 7) without mortality.
The mortality was significantly higher in the group with clinical treatment (P = 0.0189). The comparative study about the mortality of each group of TIMI score was not statistically significant: there was no correlation of TIMI score and mortality.
